Hi, my NIS2007 installed in a Windows XP Pro SP2 PC is able to update everything except this update which fails:

"Symantec Security Software" that includes these two components:
Symantec Known Application System (552.3kb)
White List (194.2kb)

The following error is displayed after the LiveUpdate session:

"LU1821: This update failed because it tried to overwrite a file that was in use. Close all of your Symantec applications and run LiveUpdate again."

I went thru the steps outlined in the link below to repair LiveUpdate without success (the above symptom repeats):

Any ideas to fix this? Thanks
